Four people were discovered dead Saturday inside a suburban Denver home following a barricade hostage situation, which drew in a team of 40 officers. One woman reportedly escaped the townhome, although it is unclear whether or not she sustained injuries. Officials first arrived on the scene close to 3 a.m. Saturday following reports that shots had been fired inside the home. The "armed and dangerous" man is reported to be among the deceased. The identities of the victims have yet to be released.
A SWAT team arrived in the area after a standoff took place between the gunman and police officers. Authorities said the gunman then shot at SWAT team members.
Police were initially unsure how many people were barricaded inside the home. Officers later confirmed that three people were found dead inside the home when SWAT moved in and shot the gunman.
Authorities said a fifth person managed to get out of the house. The identities of the victims and the suspect have not been released.
Tear gas was deployed into the home, according to police scanner traffic.
Police had evacuated several neighborhoods in the area for safety reasons.
Just last summer, a mass shooting occurred inside of the Century movie theater in Aurora, Colorado, during a midnight screening of the film "The Dark Knight Rises." A gunman, dressed in tactical clothing, set off tear gas grenades and shot into the audience with multiple firearms, killing 12 people and injuring 58 others. James Eagan Holmes, the lone suspect, was arrested outside of the theater just moments later.
